Abstract: in this article a new laser-radar ranging equation is deduced. This equation takes into consideration the tracking jitter of a telescope and the beam jitter caused by atmosphere turbulence.

The video tracker controls a mirror to acquire the Relay Mirror Experiment (RME) satellite, and provides a robust low bandwidth tracking loop to remove line of sight jitter.

视频跟踪器控制反射镜以捕获中继反射镜实验（RME）卫星，并提供鲁棒性强的低带宽增益视频跟踪回路，从而消除视轴抖动。

The method that widened tracking gate was always used to deal with PRF jitter radar in the modern signal selection technology, but it would result in some exclusive signal in the wide gate.

在现代信号分选技术中对付重频抖动雷达的方法主要是加宽跟踪波门，这样会使宽波门内出现异部信号。

As OEMs also look to implement more flexible input options for consumers, the Synaptics ClearPad 3400 allows simultaneous pen and finger touch recognition, passive pen tracking with pinpoint accuracy, and linearity and jitter control that functions with any number of fingers and styluses as small as 2mm.
